Nowadays in the eyeglasses market, multifocal prescription glasses especially progressive glasses are becoming more and more popular among the people who has both eye problems in seeing either at distance or near(such as reading books). In the past, they always need to back-up two pairs of prescription glasses and change them in different environment which is very inconvenient. With the appearance of the progressive glasses, they can see both far and near distance clearly with only one pair of prescription glasses.

Progressive glasses which is also called progressive addition lenses (PAL) or no-lined bifocal glasses has three vision fields, the top portion of the lens corrects for far distance, narrowing to the lower middle for mid-range, finally to the bottom portion for the near-vision or reading. The three vision fields for progressive prescription glasses are gradient increasing. The gradient usually starts at a minimum or no addition power at the top then reaches to a maximum addition power at the bottom of the lens for your prescription glasses. During the wearing of the progressive prescription glasses, many people may encounter different problem, here we would provide you some suggestion about choosing one pair of suitable progressive glasses for your reference.

The first and important factor you should take into consideration for such progressive prescription glasses should be the frame option. Since the design of such lenses has more than one vision field which will cause each of the certain vision field reduce to some extent, you are advised to choose frames with the higher lens height (at least 28mm). And if the frame you choose for the progressive prescription glasses is too small, the reading portion of the lens would sometimes reduce a lot which will cause discomfort to you after the lens was cut and inserted to the frame.

Apart from that, you should also pay attention to the wear locations for the progressive glasses. Since the different wear location might decide how to assemble it, and if you dont make sense of it, the prescription glasses you received are most likely to be unworkable for you. For example, if you want the prescription glasses to be worn all the way up on your nose (almost touching the forehead), you should assemble the reading portion lower down to satisfy your requirement.

What is more worth mentioning is that an adjustable nose pads for the progressive prescription glasses can also do a great of help to make sure the comfort of glasses wearing since you can push the nose pads closer or apart by yourself to change the near segment.
